' C ONCRETE CONSTRUCTION.

Application filed February 15, 1924. Serial No. 692,965.

This invention relates to concrete constructions, and more particularly,it is directed to improvements in means for tying brick, tile, or stoneveneer to the concrete wall.

An object of theinvention is to provide a wall tie of the characterdescribed which shall facilitate, to a high degree, the positioning ofanchor members for tying in the brick, stone veneer, tile, or the likeconstruction, to the concrete wall, and which shall enable such anchormembers to be inserted in position without breaking or otherwisemutilating the concrete wall.

Another object of theinvention is to provide a wall tie of the characterdescribed which can be easily and quickly attached to.

the mold and which will be securely retained in the concrete wall afterthe concrete is poured.

A further object is to provide a walltie of the character describedwhich shall be eflicient in operation and economical in use to and yetcomparatively cheap to manufacture.

Other objects of this invention will in part be obvious and in parthereinafter pointed out.

The invention accordingly consists in the features of construction,combinations of elements and arrangement of parts which will beexemplified in the construction hereinafter described and of which thescope of application will be indicated in the following claims.

In the accompanying drawing, in which is shown one of the variouspossible illustravt-ive embodiments of this invention,

Fig. 1 is a perspective view partly in sectionshowing a portion of aconcrete wall and mold therefor with tie members, embodying theinvention, shown inuse;

Fig. 2 is a perspective view of a portion of the wall tie, showing thesupplementary retaining means;

Fig. 3 is a partial sectional view, taken transverse to the length ofthe tie-member,

which is shown attached to the mold, and before pouring of the concrete;

Fig. 4 is an. enlarged perspective view of the tie-member, embedded inthe concrete wall, as shown in Fig. 1, illustrating the insertion of theanchor member; and

Fig. 5 is a partial sectional view taken transverse the length of theembedded anchoring conduit, showing the anchor member and the veneerfacing attached to the concrete body.

Referring in detail to the drawing, my invention is there shown inconnection with a mold 15 into which the concrete is poured so as toprovide a concrete Wall 13 and to which is bonded a veneer facing suchas brick 19 or tile or the like.

The wall tie, embodied in my invention and illustrated in the drawing,as best shown in Fig. 2, will be seen to comprise a channel member 10,made of metal or other suitable material, having the channel opening 11thereof tapered, the side walls 10 of the channel member taperingtowards each other away from the rear. attaching or supporting wall 12,whereby the channel member is secured to the concrete wall. Forproviding additional and efficient securing means for positivelyanchoring the channel member in the concrete wall, I further provideanchoring arms 14, preferably by punching the wall 12, each arm beingstamped into loop form of any desired shape as in the drawing. Howeverthey may be made circular in shape, or of any other triangular orirregular shape.

In the stamping up of the anchoring arms 14 from the rear wall 12,openings 14L are provided in the rear wall 12 of the channel memberwhich serve the purpose hereinafter described.

In the practical use of my invention, a channel member such as describedis first secured to the concrete mold 15, usually of wood. To best dothis, I first insert into the channel opening 11 a strip or lath 16,preferably of tapered cross-section, tapering in a direction opposite tothe taper of the channel opening, into the channel opening 11. Due tothe structural form of the channel member 10, the edges of the side wall10 thereof will grip the strip 16 and will firmly secure said member 10in place. I then secure the channel member to the mold 15 by means ofnails 17 passing through the openingsl i, the lath 16,

and the mold 15 (see Fig. 3). The concrete I by the anchor arms 14, butnot entering the channel opening 11 which is closed by the lath 16.After the concrete is hardened, the mold '15 and laths 16 are removed,leaving the channels embedded, as shown best in Fig. 4 with the channelopening ready to receive the anchor members, such as 21. For tying inthe veneer facing, brick, tile or the like, 20 to the concrete wall, thebrick or tile 19 is laid in the usual manner with the cement bindingmaterial such as mortar 20 between the concrete wall and each layer ofbrick or tile as shown in Figs. 1 and 5. Theanchor members 21 have atapered head portion21 conform and interlock with the channel opening11, as shown in Figs. 1 and 5, for quick and easy insertion in thechannel, as best seen in Fig. 4:, the anchor member 21 being firstinserted, with the head 21 sidewise, into the channel opening, and thenturned into posi= tion to look into the channel as will be readilyunderstood. Extending from the head member 21 are leg members 21,adapted to rest on the brick or tile, as will be readily understood. Thelength and spread of these members may, of course, be modified so as tobest adapt the anchor member for various thicknesses and types of veneerfacing. Thus, Where tile is employed, a shorter anchor piece will beneeded, while a longer one would be used Where brick is employed.

' It will thus be seen that there is provided a device in which theseveral objects of this invention are achieved and which is Well adapted to meet the conditions of practical use.

As various possible embodiments might be made of the above invention andas various changes might be made in the embodiment above set forth, itis to be understood that all matterherein set forth or shown in theaccompanying drawings is to be interpreted as illustrative and not in alimiting sense.

' Having thus described my invention I claim as new and desire to secureby Letters Patent 1. In combination with a cementitious body, a tie-member' comprising a metallic member having an opening lengthwisethereof and shaped to be retained when embedded in a cementitious bodywith the said opening adjacent the outside surface thereof, said memberhaving punched and bent portions to form supplementary anchoring means,a looped anchor member having a bight portion shaped to enter the saidopening and spring leg portions adj ustably interlocking along thelength of the tie member, said tie member and supporting members adaptedto anchor for binding veneer facing sections to said body.

2. 1n a concrete construction, in combination with a wall tie memberhaving a tapered channel opening, a looped anchor member having a bightportion adapted to engage in said channel opening, and diverging springleg portions extending from said head member for adjustably interlockingalong the tie member.

31A step in the art of molding concrete with a channel Wall tie memberembedded therein consisting in securing the tiemember to a strip so asto 'cover a perforated portion of said member and fastening said stripand tie member in place on a wall of a mold.

In testimony whereof I affix my signature.
